clean up unused imports
add APIResponse tests and some convenience methods

Also make Account and APIExecutor test compile post changes
test the string utilties
dependencies appear to need to be compiled in?
don't verify certificates...yet

also, do some logging when we hit the API.
refactor APIRequest and test against example from API reference
add testing properties template file

Folks using this system on their own will obviously have to generate their own
test data for now, because it's not safe for me to share my own account data!
keep the betamax tapes directory, but not the tapes

Not until I get more requests working will I be comfortable changing
the output of the tapes after each practice run.
